system engages and disengages the clutch to control  
pressure. To prevent unnecessary wear to the clutch, it is  
advisable to adjust the engine speed and pressure setting to  
limit the amount of times the clutch engages and disengages.  
To reduce clutch wear, refer to the following examples.  
Replacing the PRIME/SPRAY Valve  
Perform the following procedure using PRIME/SPRAY valve  
replacement kit P/N 0507690.  
1. Drive the groove pin out of the valve handle.  
2. Remove the valve handle and the cam base.  
3. Using a wrench, loosen and remove the valve housing  
assembly.  
Example:  
4. Make sure the gasket is in place and thread the new valve  
housing assembly into the filter housing. Tighten securely  
with a wrench.  
5. Place the cam base over the valve housing assembly.  
Lubricate the cam base with grease and line up the cam  
with the filter block using the dowel pin.  
Operating one gun with a .019 tip — reduce the engine speed  
by adjusting the throttle to a low or medium setting and  
increase pressure only until the heavy ends of the spray  
pattern have been eliminated.  
Example:  
Operating one gun with .023 tip — increase engine speed to a  
high setting and increase pressure until the heavy ends of the  
spray pattern have been eliminated.  
6. Line up the hole on the valve stem with the hole in the  
valve handle.  
7. Insert the groove pin into the valve handle and through  
the valve stem to secure the valve handle in position.  
Example:  
Spraying light-bodied materials at low pressure — to reduce  
surging at the gun and to decrease clutch wear, reduce the  
engine speed to idle and reduce pressure until the desired  
spray pattern is achieved.

used to gently tap the assembly into position.  
16. Make sure the friction surface of the clutch armature is  
clean and free from oil or grease.  
Removing the Clutch Rotor, Clutch Field, and  
Drive Shaft Assembly  
1. Follow steps 1–7 in “Removing/Replacing the Clutch Hub  
and Armature Assembly.”  
2. Locate the clutch rotor assembly on the end of the drive shaft  
assembly. Note the locations of the three socket screws and  
the two empty, threaded holes on the clutch rotor.  
3. Using a 3/16” hex wrench, remove the three socket  
screws and lock washers that secure the clutch rotor to  
the drive shaft assembly.  
4. Thread two of the socket screws into the empty, threaded  
holes and tighten alternately. This will push the clutch  
rotor away from the drive shaft assembly and pinion.  
CAUTION  
Do not force the drive shaft assembly into position.  
3. Install the retaining ring into its groove next to the large  
ball bearing.  
4. Line up the four holes around the outside of the clutch  
field with the four set screw holes in the gear housing.  
The clutch field wires should be at approximately the 1 or  
2 o’clock position.  
5. Route the two clutch field wires through the grommet and  
into the EPC housing.  
6. Carefully slide the clutch field into its bore in the gear  
housing until it “bottoms out” within the housing. Do not  
pinch the clutch field wires during installation.  
WARNING  
Electrostatic discharge (ESD) potential could cause  
damage to electronic pressure control. Use SprayTECH  
ESD wrist strap P/N 0507958 or equivalent when working  
on electronic pressure control.  
NOTE: Apply blue Loctite to the four clutch field set  
screws prior to installation.

7. Thread one of the set screws into its hole. Using an 1/8”  
hex wrench, rotate the screw slowly until it contacts the  
clutch field. Do not tighten the set screw. The tip of the  
set screw should mate with the drill point hole in the field.  
Check the clutch field for rotation. If it rotates within its  
bore, the set screw is not seated within the drill point.  
2. Check the gap between the clutch armature and the clutch  
rotor using a .016” feeler gauge and a .035” feeler gauge.  
a. Insert each feeler gauge through the port and into the  
gap between the clutch armature and the clutch rotor.  
The .016” feeler gauge should fit in the gap. The .035”  
feeler gauge should not fit in the gap.  
8. When the set screw is properly seated, install the remaining  
three set screws. Do not tighten the set screws.  
9. Using a crossing pattern, tighten each of the setscrews  
until they are snug. Once all four set screws are snug,  
use a crossing pattern to tighten and torque the set  
screws to 60–70 in./lbs.  
b. Pull the engine pull cord several times to rotate the  
clutch armature, checking the gap with each feeler  
gauge between each pull.  
c. If the .016” gauge does not fit or the .035” gauge does  
fit at any checkpoint, the gap must be readjusted. This  
is done by relocating the clutch hub and armature  
assembly on the engine shaft. Refer to the  
“Removing/Replacing the Clutch Hub and Armature  
Assembly” procedure.  
CAUTION  
It is very important to evenly snug, tighten, and torque the  
clutch field set screws in a crossing pattern. This ensures  
the clutch field will stay centered in the gear housing.  
10. Line up the three screw holes and dowel pin hole on the  
clutch rotor with the screw holes and dowel pin on the drive  
shaft assembly hub. Place the clutch rotor onto the hub.  
11. Using a 3/16” hex wrench, thread the three socket screws  
and lock washers through the clutch rotor and into the  
drive shaft assembly hub. Evenly snug, tighten, and  
torque the socket screws to 75–85 in/lbs.  
12. Make sure the friction surface of the clutch rotor is clean  
and free from oil or grease.  
Servicing the Fluid Section  
Use the following procedures to service the valves and repack  
the fluid section.  
1. Start the engine (refer to the procedures in the Operation

AVERTISSEMENT AUX MÉDECINS : Une perforation  
sous-cutanée constitue un traumatisme. Il est  
important de traiter la blessure de façon chirurgicale  
aussitôt que possible. NE RETARDEZ PAS ce traitement  
pour des recherches de toxicité. La toxicité n'est un  
risque que dans les cas où certains produits de  
revêtement pénètrent dans le flux sanguin. Il peut être  
nécessaire de faire appel à des soins de chirurgie  
plastique ou de reconstruction de la main.  
Consignes de sécurité  
Le présent manuel comprend des renseignements devant être  
lus attentivement avant toute utilisation de l'appareil. Lorsque  
l'un des symboles suivants apparaît, il est recommandé d'être  
particulièrement attentif et de tenir compte des mesures de  
sécurité indiquées.  
AVERTISSEMENT  
Ce symbole indique un danger potentiel pouvant causer des  
blessures graves ou même mortelles. Des renseignements  
importants sur la sécurité sont également indiqués.  
DANGER: RISQUES D'EXPLOSION OU D'INCENDIE - Les  
vapeurs dégagées par le solvant ou la peinture  
sont explosives et inflammables et peuvent  
causer des corporels sérieux ou dommages  
matériels.  
ATTENTION  
MESURES PRÉVENTIVES:  
Ce symbole indique un danger potentiel pouvant causer des  
blessures corporelles ou des dommages à l'équipement. Des  
renseignements importants sur la façon de prévenir tout  
dommage à l'équipement ou toute blessure corporelle mineure  
sont également indiqués.  
• Veiller à éviter toute accumulation de vapeurs  
inflammables en vous assurant que la zone où la  
pulvérisation a lieu est suffisamment ventilée.  
• Veiller à éviter la présence de toute source incandescente  
telle qu'étincelle électrostatique, flamme nue, flamme-  
pilote, objet brûlant, cigarette et étincelle provenant du  
branchement ou du débranchement d'un cordon  
d'alimentation électrique ou d'un commutateur.  
NOTA : Les remarques donnent des renseignements  
importants requérant une attention particulière.  
• Ne pas fumer dans la zone d’épandage.  
Toujours avoir un extincteur en état de fonctionner à  
portée de la main.  
AVERTISSEMENT  
DANGER: BLESSURES PAR PERFORATION - Le jet de  
peinture à haute pression produit par cet  
appareil peut perforer la peau et les tissus  
sous-jacents et entraîner de sévères blessures  
pouvant nécessiter une amputation. Consultez  
immédiatement un médecin.  
NE PAS TRAITER UNE BLESSURE PAR PERFORATION  
COMME UNE SIMPLE COUPURE! Une perforation peut  
entraîner des risques d'amputation. Consultez  
immédiatement un médecin.  
• Placer la pompe à peinture à une distance d’au moins un  
mètre (3 pi) (on recommande d’ailleurs une plus grande  
distance) de l’objet qui doit être vaporisé dans une pièce  
séparée bien aérée, ou à une distance d’au moins six  
mètres (20 pi) de celui-ci dans une zone bien aérée  
(utiliser d’autres tuyaux si nécessaires). Les vapeurs  
inflammables sont souvent plus lourdes que l’air. Le  
plancher doit être extrêmement bien aéré. La pompe à  
peinture contient des pièces pouvant créer des étincelles  
et enflammer les vapeurs présentes dans l’air.  
Pression de service maximale du fluide dans l’appareil :  
3300 lb/po2 / 22. 8 MPa.  
• Le matériel utilisé, ainsi que les objets se trouvant à  
proximité de la zone de pulvérisation, doivent être  
convenablement reliés à la terre afin d'éviter toute  
étincelle ou toute décharge électrostatique.  
• N'utiliser que des flexibles d'alimentation en liquide à  
haute pression conducteurs ou reliés à la terre dans les  
cas d'utilisation sans air comprimé. S'assurer que le  
pistolet est convenablement relié à la terre par  
l'intermédiaire du flexible.  
MESURES PRÉVENTIVES:  
• NE JAMAIS diriger le pistolet vers une quelconque partie  
du corps.  
• NE JAMAIS mettre une quelconque partie du corps en  
contact avec le jet de liquide. NE JAMAIS se mettre au  
contact d'un jet de liquide provenant d'une fuite du flexible  
d'alimentation en liquide.  
• NE JAMAIS placer votre main devant le pistolet. Des  
gants ne vous protégeront pas contre les risques de  
blessures par perforation.  
• TOUJOURS verrouiller la gâchette du pistolet, fermer la  
pompe à liquide et décompresser l'appareil lorsque vous  
travaillez sur celui-ci, nettoyez le protecteur de tête,  
remplacez la tête de pulvérisation ou vous éloignez de  
l'appareil. Couper le moteur ne décompresse pas l'appareil.  
Vous devez, pour le décompresser, placer le bouton  
AMORÇAGE/PULVÉRISATION en position AMORÇAGE.  
Reportez-vous, pour cela, à la PROCÉDURE DE  
DÉCOMPRESSION décrite dans de ce manuel.  
• TOUJOURS s'assurer que le protecteur de tête est en  
place lorsque vous pulvérisez. Le protecteur de tête offre  
une certaine protection contre les blessures par perforation  
mais sa principale fonction est d'ordre préventif.  
• TOUJOURS ôter la tête de pulvérisation avant de purger  
ou nettoyer l'appareil.  
• Le flexible d'alimentation en peinture peut fuir à la suite  
d'une usure, de chocs ou de mauvais traitements. Une  
fuite peut entraîner une perforation de la peau. Inspecter  
le flexible avant chaque utilisation.  
• NE JAMAIS utiliser un pistolet dont la gâchette n'est pas  
munie d'un loquet ou un cran de sécurité qui soit en état  
de fonctionner.  
• Le cordon d’alimentation doit être raccordé à un circuit  
mis à la terre.  
Toujours purger l’appareil dans un contenant métallique  
séparé, en s’assurant que la pompe soit à basse pression  
et que le chapeau soit retiré. Tenir le pistolet fermement  
contre la paroi du contenant pour mettre celui-ci à la terre  
et empêcher l’émission d’étincelles causées par  
l’électricité statique.  
• Se conformer aux consignes et recommandations de  
sécurité du fabricant du solvant ou du produit.  
• S’entourer de toutes les précautions possibles lorsqu’on  
utilise des produits ayant un point d’éclair inférieur à 21  
°C (70 °F). Le point d’éclair d’un fluide est la température  
à laquelle les vapeurs émanant du fluide peuvent  
s’enflammer au contact d’une flamme ou d’une étincelle.  
• Le plastique peut être une source d’étincelles provoquées  
par l’électricité statique. Ne jamais utiliser une couverture  
en plastique pour fermer une zone d’épandage ni utiliser  
des toiles de protection en plastique lors de la  
pulvérisation de matières inflammables.  
• Lorsque vous purgez l'appareil, veillez à utiliser à la  
pression minimale.  
Tous les accessoires doivent être homologués pour une  
pression égale ou supérieure à 3300 lb/po2 / 22. 8 MPa.  
Cela s'applique, entre autres, aux têtes de pulvérisation,  
aux accessoires du pistolet et aux flexibles.

entre la pompe et un objet mis à la terre, tel qu’une conduite  
d’eau métallique. Se reporter au guide d’utilisation du moteur  
pour obtenir de plus amples renseignements concernant la  
sécurité.  
DANGER: RISQUES D'EXPLOSION PAR INCOMPATIBILITÉ  
DES MATÉRIAUX - Peuvent être à l'origine de  
corporels sérieux ou dommages matériels.  
MESURES PRÉVENTIVES:  
• Ne pas utiliser de matériaux contenant des agents de  
blanchiment ou du chlore.  
• Ne pas utiliser des solvants à base d’hydrocarbure  
halogéné tels que l’agent anticryptogamique, le chlorure  
de méthylène et le trichloro-éthane-1,1,1. Ces produits ne  
sont pas compatibles avec l’aluminium  
• Communiquer avec votre fournisseur de revêtement pour  
connaître la compatibilité du matériau avec l’aluminium.  
3. Tenez les enfants et les animaux domestiques à l'écart de  
la zone de travail; vous éviterez ainsi tout risque de  
brûlures sur les pièces chaudes du moteur et de  
blessures entraînées par les accessoires utilisés par le  
moteur pour son fonctionnement.  
DANGER: VAPEURS NOCIVES – la peinture, les solvants,  
les insecticides et autres matériaux peuvent  
être nocifs lorsqu’ils sont inhalés ou en contact  
avec le corps. Les vapeurs peuvent causer une  
nausée importante, des évanouissements ou  
un empoisonnement.  
4. Sachez comment arrêter rapidement le moteur, et  
assurez-vous que vous avez bien compris le  
fonctionnement de toutes les commandes. Ne permettez  
jamais à une personne de faire fonctionner le moteur sans  
connaître les instructions nécessaires.  
MESURES PRÉVENTIVES:

NO retrase el tratamiento por investigar la toxicidad.  
La toxicidad es motivo de preocupación con algunos  
revestimientos que se inyectan directamente en la  
corriente sanguínea. Es recomendable consultar a un  
cirujano plástico o reconstructor de manos.  
Precauciones de seguridad  
Este manual contiene información que debe leer y comprender  
antes de usar el equipo. Cuando se encuentre con uno de los  
siguientes símbolos, asegúrese de observar sus indicaciones  
de seguridad.  
ADVERTENCIA  
Este símbolo indica la existencia de un peligro potencial que  
puede causar lesiones graves o la muerte. Después del  
mismo se incluye información de seguridad importante.  
PELIGRO: EXPLOSIÓN O INCENDIO - Los vapores de  
solventes y pintura pueden explotar o  
incendiarse, causando con esto lesiones  
severas y/o daños en la propiedad.  
PARA PREVENIR:  
PRECAUCION  
Este símbolo indica la existencia de un peligro potencial para  
usted o el equipo. Después del mismo se incluye información  
importante que indica la forma de evitar daños al equipo o la  
forma de prevenir lesiones menores.  
• Debe proveerse un escape y aire fresco para hacer que el  
aire que está dentro del área de atomización se mantenga  
libre de acumulaciones de vapores inflamables.  
• Evite todas las fuentes de ignición como son las chispas  
electrostáticas, llamas abiertas, flamas de piloto, objetos  
calientes, cigarros, y chispas que se generan al conectar  
y desconectar las extensiones o de apagadores de luz  
que estén funcionando.  
NOTA: los avisos contienen información importante,  
présteles especial atención.  
• No fume en la zona de trabajo.  
• Debe haber un equipo para extinguir incendios  
permanentemente y en buenas condiciones.  
ADVERTENCIA  
• Coloque la bomba para pintar a un mínimo de 1 m (de  
preferencia más) en una habitación aparte, bien ventilada,  
alejada del objeto que va a pintar o a por lo menos 6 m  
de dicho objeto, en una zona bien ventilada (utilice una  
manguera más larga, si es necesario). Los gases  
inflamables a menudo son más pesados que el aire. La  
zona del piso debe tener la debida ventilación. La bomba  
para pintar contiene piezas que forman arcos que emiten  
chispas y pueden encender los gases.  
• El equipo que se utilice, así como los objetos que estén  
dentro y alrededor del área de atomización, deben  
conectarse a tierra de manera apropiada para prevenir las  
descargas eléctricas y las chispas.  
PELIGRO: LESIÓN POR INYECCIÓN - La corriente de  
pintura de alta presión que produce este  
equipo puede perforar la piel y tejidos  
subyacentes, lo que conduciría a lesiones  
serias y una posible amputación. Consulte de  
inmediato a un médico.  
NO TRATE LAS LESIONES POR INYECCIÓN COMO SI  
FUERAN SIMPLES CORTADAS! Una inyección puede  
conducir a una amputación. Consulte de inmediato a un  
médico.  
El rango de operación máximo de la unidad es 3300 PSI /  
22.8 MPa de presión de fluidos.  
PARA PREVENIR:  
• Use solamente mangueras para fluidos de alta presión,  
conductoras o conectadas a tierra, para aplicaciones sin  
aire. Asegúrese de que la pistola esté conectada a tierra  
de manera apropiada, mediante conexiones de  
manguera.  
• NO dirija NUNCA la punta de la pistola hacia alguna parte  
del cuerpo.  
• NO permita NUNCA que alguna parte del cuerpo tenga  
contacto con la corriente del fluido. EVITE tener contacto  
con corrientes de fluido que salgan de fugas que haya en  
la manguera.  
• El cable de alimentación debe enchufarse a un circuito  
aterrado.  
• NO ponga NUNCA la mano enfrente de la manguera. Los  
guantes no ofrecen ninguna protección contra lesiones  
por inyección.  
• Siempre enjuague la unidad en un recipiente de metal por  
separado, con presión baja en la bomba y sin la boquilla.  
Sostenga la pistola firmemente contra el recipiente para  
ponerlo a tierra y evitar chispas estáticas.  
• Siga las advertencias y avisos de seguridad del fabricante  
de los materiales y solventes.  
Tenga muchísimo cuidado al usar materiales cuyo punto  
de ignición sea inferior a 70° F (21° C). El punto de  
ignición es la temperatura a la cual pueden encenderse  
los vapores emanados por un fluido al exponerlos a  
llamas o chispas.  
• El plástico puede causar chispas estáticas. Nunca  
cuelgue plástico en las ventanas ni en las puertas del  
área donde va a pintar. No utilice plástico para proteger  
el piso cuando pinte materiales inflamables.  
• Bloquee SIEMPRE el gatillo de la pistola, apague la  
bomba de fluido y libere toda la presión antes de dar  
mantenimiento, limpiar el protector de la boquilla, cambiar  
la boquilla o dejar desatendido el equipo. La presión no  
se liberará al apagar el motor. Para liberar la presión  
debe girarse la perilla PRIME/SPRAY (cebar/atomizar)  
hasta la posición PRIME. Consulte el PROCEDIMIENTO  
PARA LIBERAR LA PRESIÓN que se describe en este  
manual.  
• Mantenga puesto SIEMPRE el protector de la boquilla  
mientras atomice. El protector de la boquilla ofrece cierta  
protección contra lesiones por inyección pero es  
principalmente un dispositivo de advertencia.  
• Quite SIEMPRE la boquilla del atomizador antes de  
enjuagar o limpiar el sistema.  
• Pueden desarrollarse fugas en la manguera de pintura  
por causa del desgaste, retorcimientos o el abuso. Una  
fuga es capaz de inyectar el material en la piel. Cada vez  
que use la manguera de pintura, inspecciónela antes.  
• Cuando enjuague el equipo utilice la presión más baja  
posible.  
MOTOR DE GAS (SEGÚN CORRESPONDA)  
Coloque siempre la bomba fuera del edificio, al aire libre.  
Mantenga todo solvente alejado del escape del motor. Nunca  
llene el tanque de combustible si el motor está encendido o  
caliente. La superficie caliente puede encender el combustible  
derramado. Conecte siempre un conductor de tierra desde la  
unidad de la bomba a un objeto puesto a tierra, por ejemplo  
una tubería de agua metálica. Consulte el manual del motor  
para obtener información completa de seguridad.  
• NO use nunca una pistola de atomización que no tenga  
un bloqueador o un protector de gatillo puesto y que  
funcione.  
Todos los accesorios deben tener una capacidad de 3300  
PSI / 22.8 MPa o mayor. Esto incluye las boquillas de  
atomizador, pistolas, extensiones y mangueras.

4. Conozca el modo de detener rápidamente el motor, y  
entienda el funcionamiento de todos los controles. No  
permita que nadie haga funcionar el motor sin las  
instrucciones adecuadas.  
PARA PREVENIR:  
• No utilice materiales que contengan blanqueador o cloro.  
• No use solventes con hidrocarburos halogenados, tales  
como productos para eliminar el moho, cloruro de  
metileno y 1,1,1 - tricloroetano. Estos no son compatibles  
con el aluminio.  
• Comuníquese con el proveedor del producto para obtener  
información de compatibilidad con materiales de aluminio.  
PELIGRO: GASES PELIGROSOS - Las pinturas, solventes,  
insecticidas y otros materiales pueden ser  
perjudiciales si se inhalan o entran en contacto  
con el cuerpo. Los gases pueden causar  
náusea, desmayos o envenenamiento graves.  
PARA PREVENIR:  
• Use una mascarilla respiratoria o careta siempre que  
exista la posibilidad de que se puedan inhalar vapores.  
Lea todas las intrucciones que vengan con la careta para  
estar seguro de que se tendrá la protección necesaria  
contra la inhalación de vapores dañinos.  
• Use gafas protectoras.  
• Use ropa de protección, según lo requiera el fabricante  
del producto.  
PELIGRO: GENERAL - Puede causar daños en la  
propiedad o lesiones severas.  
PARA PREVENIR:

antes de hacer funcionar cualquier equipo.  
• Desconecte siempre el motor del suministro eléctrico  
antes de dar servicio al equipo.  
• Observe todos los códigos locales, estatales y nacionales  
apropiados que rigen las medidas de ventilación,  
prevención de incendios y operación.  
• Los Estándares de Seguridad del Gobierno de los  
Estados Unidos se han adoptado bajo el Acta de  
Seguridad y Salud Ocupacionales (OSHA por sus siglas  
en inglés). Deben consultarse estos estándares,  
particularmente la parte 1910 de los Estándares  
Generales y la parte 1926 de los Estándares de la  
Construcción.  
• Utilice únicamente piezas autorizadas por el fabricante.  
El usuario asume todos los riesgos y responsabilidades si  
usa piezas que no cumplen con las especificaciones  
mínimas y dispositivos de seguridad del fabricante de la  
bomba.  
• Antes de usarla cada vez, revise todas las mangueras para  
ver que no tengan cortadas, fugas, una cubierta desgastada  
por abrasión o con abolladuras, así como uniones dañadas  
o que se hayan movido. Si existiera cualquiera de estas  
condiciones, reemplace la manguera inmediatamente. No  
repare nunca una manguera de pintura. Reemplácela con  
otra manguera conectada a tierra.  
5. La gasolina es extremadamente inflamable y es explosiva
